An attractive specimen of superb sphalerite crystals with galena and quartz from the famous Madan ore field, Bulgaria. It displays black and sharp sphalerite octahedrons growing at the top. They have nice striations, good luster and truncated tips. The galena crystals are matt cubes. They have very sharp geometry and they show some skeletal features. Some small quartz crystals with yellow tips enrich the stand.  It is complete all over. In very good condition – some small nicks and contacts.
